In March 2019, the National Wildlife Federation (NWF), a conservation organization working across the U.S., published a report called New Research Findings Link Biofuel Mandate to Environmental Harm. According to the report, the U.S. Renewable Fuel Standard (RFS) and its implementation are leading to environmental disaster which involves the destruction of the monarch butterfly habitat, climate change acceleration, and drainage of western aquifers, amongst other issues. The research referred to in the NWF report was prepared by the University of California-Davis, University of Wisconsin, and Kansas State University. Scientists at the aforementioned institutions have assessed the direct connection between the U.S. biofuels policy and specific economic and field-level environmental changes since RFS’ inception ten years ago. The report summarizes some of these connections and outlines measures Congress and the Administration must take to prevent further damage.
